PAHLAA - a loud cry you make when something happens that is both awes

a loud cry you make when something happens that is both awesome and terrible at the same time

I got a new phone but it broke right away and I yelled 'PAHLAA!' because I was confused.

I got ice cream and it was melted and I cried 'PAHLAA!' because I was sad.

I won a prize but had to run a race and I screamed 'PAHLAA!' because I was stressed.
